Speccation of Iietters Patent.

Patented Dee. 17. 1907. 1

Application nea May-:17. 1906. serial No. 317.317.'

Be it known that I, FINLAY RoBEI-:T Mo- QUEEN, a citizen of the United States,'residl ingat Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Grain-Storage Elevators; and I do hereby declare the following to be a full, clear, and

exact description of the invention, such as ,will enable others skilled in the art to which j it appertains to make and use the same.

` My present invention relatesY to grain stor- `age elevators, and particularly to concrete or .concrete steel, or other iire-proof structures,

wherein a multiplicity of cylindrical bins arelemployed, the said bins being placed in close- 'juXta ositionwiththe space between the cylin rical bins arranged to serve as supplemental storage bins. l,

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described and defined in the grain bins, which bins are arranged in rows vin two directions, and are formed monolithic, or otherwise rigidly united at their adjoining peripheral portions, so that there is left between each 'four bins, a supple- V:mental bin or storage space 2.

It will be noted that by arrangement of the cylindrical bins in rows in two directions, the intersecting'rows, extending approximately at right angles to each otherLa foursided supplemental bin is formed between each four adjoining cylindrical bins.

The numeral 3 indicates a bifurcated elevator leg oftheusual construction and in which works ap owei' driven, endless, cupequippedwbelt 4. The branches of this elevator leg'S are passed vertically through the adjacent supplemental bins 2; and the'said supplemental bins through'whichv the said legpasses are formed with vertical webs or partitions 5 that form leg passages from top to bottom of the bins, and separateI the said leg passages from the respective supplemental bins 2. 'Any desired number of the supplemental bins 2 may be thus formed with'the leg passages 6.

With the construction above described, the elevator leg is thoroughly protected from lateral pressure of the grain in the bins, and the said leg may be removed, at any time, or repaired without opening up any of the said grain bins. Furthermore, the ve tical webs o r partitions 5 increase the rigidity of the entire bin structure,

It will of course be understood that the bins above described may be constructed either of concrete, brick, or other material, and the same usually will, in practice, be reinforced by embedded steel members.

. The term masonry is herein used in-a sense broad enough to include either concrete, brick, .tile or similar material.

In the arrangement of the bins illustrated in the drawings, the said bins are assumed to be sup orted with their lowerends above the groun The main bins 1, as well as the supplemental bins 2, will, of course, be rovided with lhopper bottoms of the usual) suitable construction. j

-In Fig. 1, the numeral 7 indicates railway tracks which run along the side of the o'roup of bins; and the numerals 8 and 9 indicate hoppers located below the tracks and ada ted to receive grain from cars standing on t e tracks, and to deliver the same to conveyers 10 shown by dotted lines only in Fig. 1, and by full lines in Fig. 2. These conveyers 10 deliver the grain to its 1 1, in which pits the lower, extremities o the elevator legs 3 terminate, and from which pits the elevator belts 4 take up the grain. The elevator belts 4 deliver the grain to discharge spouts 12 at the upper ends of the legs From the spout 12, the grain may be delivered to the 10G other bins by the usual or any suitable distributing spout, (not shown). f

Certain of the bins 1 that-are at the exterior oi the structure are tied'together by ver- -tical reinforcing ribs vor webs 13 that coper- 105 ate with the diverging portions of the said bins 1, to form angular spout passages 14 through which grain delivery spouts 15.. are ada ted to be passed.

T e construction above described, while simple, and adding little c'ost tothe struc? ture, adds great strength'thereto and effects great economy in the use ofy space. l

` What I claim is that extend across angular portions ofcertain of said supplemental-buis 2, and form Verticalleg passages 6,-,in combination with 1 bifurcated'elevator'leg's having theirbranches extended 'vertically throughf adjacent, lleg passages @substantially as described. l

2. 4A 'plurality' of cylindrical grain bins f orining a monolithic -structure and. having their adjacent peripheral portionsl rigidly A connected, and iorming supplemental storagebins in the intervening spaces, vertical vr.Webs extendingV through adjacent supple.'

inental bins to form leg'passages, in combi',-y

lnation with bifurcated elevator legs-extend# ing from below said bins through adjacent leg passages, substantially as described.
